Figure 3From: Increased dietary availability of selenium in rainbow trout (Oncorhynchus mykiss) improves its plasma antioxidant capacity and resistance to infection with Piscirickettsia salmonisEffect of the selenium supplemented diets on O. mykiss physiological traits. A Representative images of livers with hematoxylin–eosin staining of fish fed with the experimental diets SSD1, SSD5, and SS10, and their respective digital zoom of 10%. Bars = 10 µm. B and C Biochemical measurements of enzymes indicative of liver damage (n = 5). D Plasma selenium concentration of O. mykiss fed with different concentrations of selenium in the diet measured by Total X-ray fluorescence spectroscopy (TXRF) at 60 days post-treatment (dpt) (n = 3). E Hydrophilic antioxidant capacity in plasmas from O. mykiss fed with different selenium concentrations in the diet measured by oxygen radical antioxidant capacity (ORAC) assay at 60 dpt (n = 5). Different letters represent significant differences (ANOVA p < 0.05, post hoc analysis Tukey).Back to article page
